CROSS-REFERENCE TO RELATED APPLICATION

This application is a Continuation of U.S. patent application Ser. No. 14/956,508 filed on Dec. 2, 2015 which claims benefit from Korean Patent Application No. 10-2015-0073092, filed on May 26, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

BACKGROUND 1. Field

The present disclosure relates to medical image display apparatuses and methods of providing a user interface via the medical image display apparatuses, and more particularly, to medical image display apparatuses and methods of providing a user interface suitable for a user.

2. Description of the Related Art

A medical imaging system acquires medical image data of an object, displays a medical image generated based on the acquired medical image data, and provides the medical image to a user. The medical imaging system may include a medical image acquisition apparatus and a medical image display apparatus.

The medical image acquisition apparatus emits a signal toward an object and acquires medical image data related to a cross-section of an object or blood flow by using a signal received from the object in response to the emitted signal.

For example, the medical image acquisition apparatus may acquire ultrasound image data, X-ray image data, computerized tomography (CT) image data, magnetic resonance (MR) image data, positron emission tomography (PET) image data, and the like.

The medical imaging system may generate a medical image from medical image data acquired by the medical image acquisition apparatus and display the generated medical image to the user on a screen of the medical image display apparatus.

A medical image may be used to diagnose or treat a disease in a patient. To use the medical image for diagnosis and treatment of a disease, it may be necessary to move a medical image display apparatus so as to provide a medical image close to a patient or user. However, since a medical image display apparatus is generally bulky and heavy, the medical image display apparatus has to be fixedly installed at a specific place and is difficult to carry. Thus, to solve this problem, a medical image display apparatus that can be carried by a user is being developed.

As medical image display apparatuses become lighter and smaller, the user may use one hand to grip and carry a medical image display apparatus. When the user handles the medical image display apparatus using one hand, the other hand is left free. Thus, the user may conveniently use the other hand to perform other activities related to diagnosis and treatment of a patient with a disease. Thus, it is necessary to develop a user interface that allows a user to hold and use a medical image display apparatus using one hand.

Furthermore, the CT image acquisition device may acquire CT image data that represents an internal structure (e.g., an organ such as a kidney, a lung, etc.) of the object without superimposition of adjacent structures, as compared to a general X-ray apparatus. The CT image acquisition device may provide a relatively accurate cross-sectional image of an object by acquiring several tens to several hundreds of images having a thickness not more than 2 mm per second and processing the images.

An MRI image acquisition device may be a device for acquiring medical image data related to a cross-section of an object by expressing, in a contrast comparison, a strength of a MR signal with respect to a radio frequency (RF) signal generated in a magnetic field having a specific strength.

An angiography apparatus may be used to acquire medical image data related to blood vessels (an artery, a vein, etc.) of an examinee, into which a contrast medium is injected through a catheter (a tube of less than 2 mm in diameter).

According to exemplary embodiments, the medical image display apparatus 100 may be located outside a shielded room or connected to the medical image acquisition device 13 inside the shielded room.

The medical image display apparatus 100 may display a medical image by using medical image data received from the medical image acquisition device 13. The medical image display apparatus 100 may also provide a GUI for controlling the medical image display apparatus 100 or for setting a function related to an operation of displaying an ultrasound image by the medical image display apparatus 100. Furthermore, the medical image display apparatus 100 may provide a GUI for controlling the medical image acquisition device 13 or for setting a function related to an operation of acquiring medical image data by the medical image acquisition device 13.

As another example, the medical image display apparatus 100 may be connected to the server 14 by wire or wirelessly. For example, the medical image display apparatus 100 may transmit and receive data to and from a hospital server connected through a picture archiving and communication system (PACS), and perform data communication with the server 14 according to the digital imaging and communications in medicine (DICOM) standard.

The server 14 may be a server for managing medical image data. For example, the server 14 may store or update medical image data and medical records associated with each patient. The server 14 may transmit medical image data to the medical image display apparatus 100. In some exemplary embodiments, the server 14 may authenticate the medical image display apparatus 100 that attempts to access the medical image data and provide the medical image data only to the authenticated medical image display apparatus 100.

The medical image display apparatus 100 may display a medical image by using medical image data received from the server 14. The medical image display apparatus 100 may also provide a GUI for controlling the medical image display apparatus 100 or for setting a function related to an operation of displaying an ultrasound image by the medical image display apparatus 100. Furthermore, the medical image display apparatus 100 may provide a GUI for controlling the server 14 or for setting functions related to operations of acquiring, storing, and managing medical image data by the server 14.

The medical image display apparatus 100 may include an input device which may be configured to receive a user input for controlling the medical image display apparatus 100 and various devices connected to the medical image display apparatus 100. For example, the medical image display apparatus 100 may include various input devices such as a plurality of function keys, a trackball, buttons and a keyboard. However, if the various input devices are disposed on an outer surface of the medical image display apparatus 100, the medical image display apparatus 100 may become bulky.

Thus, to increase utilization of a limited space in the medical image display apparatus 100, a touch pad for performing functions of various input devices may be disposed on the outer surface of the medical image display apparatus 100 instead of the various input devices being all disposed thereon.

In particular, if the medical image display apparatus 100 includes a touch screen in which a display unit for displaying a medical image forms a layer structure with a touch pad, the medical image display apparatus 100 may become smaller and lighter in weight because the touch screen may serve as both input and output devices.

As shown in FIG. 2, according to various exemplary embodiments, the medical image display apparatus 100 may include a touch screen 110.

FIG. 2 shows an example of a touch screen provided in the medical image display apparatus 100, according to an exemplary embodiment. Although FIG. 2 shows an example where the medical image display apparatus 100 displays an ultrasound image and a UI related to the ultrasound image on the touch screen 110, exemplary embodiments are not limited thereto. According to various exemplary embodiments, the medical image display apparatus 100 may provide various types of medical images and UIs related thereto.

According to various exemplary embodiments, the medical image display apparatus 100 may display via the touch screen 110 a medical image 210 and various pieces of information being processed by the medical image display apparatus 100. For example, the medical image display apparatus 100 may display a GUI 201 for displaying information about the medical image 210 currently being displayed, a GUI 203 for setting parameters related to the medical image 210, and a GUI 205 for controlling a medical image acquisition apparatus, an external device, or a server connected to the medical image display apparatus 100.

The information about the medical image 210 may include any desired information, for example a position of a region of an object depicted in the medical image 210, a position or a size of a lesion, a position or a size of a region of interest (ROI) designated by a user, information about a text or a body marker stored together with the medical image 210, or any other desired information or combination thereof.

The parameters related to the medical image 210 may include at least one piece of information among pieces of information relating to numerical values that are set with respect to acquiring the medical image 210 displayed via the medical image display apparatus 100, numerical values that are set with respect to displaying the acquired medical image 210, and numerical values related to an object depicted in the medical image 210. The parameters related to the medical image 210 may include parameters for setting a brightness, a zoom ratio, and a color of the medical image 210 and a parameter related to correction of the medical image 210. For example, the GUI 203 may include a GUI for changing parameters related to a frequency at which an ultrasound signal is transmitted, a gain, a depth, a focus, or any other desired parameter, in order to acquire the medical image or a GUI for changing a scan mode.

A GUI for controlling a medical image acquisition apparatus, an external device, or a server connected to the medical image display apparatus 100 may include a GUI for setting a method of acquiring medical image data or a method of managing the medical image data. For example, the GUI 205 may include a GUI for setting an operating mode in which a probe connected to the medical image display apparatus 100 operates or a GUI for controlling a memory to store medical image data.

As the medical image display apparatus 100 becomes lighter and smaller, the user may use one hand to grip and carry the medical image display apparatus 100. As shown in FIG. 3, a user 5 may use the medical image display apparatus 100 by touching a touch screen 110 with one hand. When the user 5 uses the medical image display apparatus 100 with one hand, the user 5 may conveniently use the other hand to perform other activities related to diagnosis and treatment of a patient with a disease.

For example, if the medical image display apparatus 100 is connected to an ultrasound diagnosis device, the user 5 may grip an ultrasound probe of the ultrasound diagnosis device with one hand and the medical image display apparatus 100 with the other hand. The user 5 may move the ultrasound probe to a position corresponding to an area of interest in a patient so that the ultrasound probe may acquire ultrasound image data of the area of interest. Simultaneously, in order to be provided with an optimized ultrasound image, the user 5 may control operations of the ultrasound diagnosis device and the medical image display apparatus 100 related to acquisition and display of an ultrasound image by using the medical image display apparatus 100. Thus, the medical image display apparatus 100 may provide the user 5 with an optimized ultrasound image of a desired area in real-time.

In some exemplary embodiments, while the user grips the medical image display apparatus 100 with one hand, a region that may be touched or covered by a finger of the user 5 may be limited. For example, as shown in FIG. 3, a region that may be accessible to a finger of the user 5 may be limited to a region 301, marked with diagonal lines. Thus, according to exemplary embodiments, a method and a medical image display apparatus for providing a UI based on a touch range of a finger of the user 5 may be provided.

According to various exemplary embodiments, the medical image display apparatus 100 may provide a UI based on a touch range of a finger of the user 5. For example, referring to FIG. 4, a medical image display apparatus 100 according to an exemplary embodiment may display a UI 401 within a region 301 that may be touched by a finger of a user 5.

A method of providing, by the medical image display apparatus 100 of FIG. 4, a UI based on a size of a touch range of a finger of a user according to an exemplary embodiment will now be described in more detail with reference to FIG. 5.

FIG. 5 is a flowchart of an exemplary method of providing, by the medical image display apparatus 100, a UI based on a size of a finger-touchable range, according to an exemplary embodiment. In some exemplary embodiments, “finger-touchable” may be used to indicate, for example, accessible by a finger, or “finger-accessible.”

Referring to FIG. 5, the medical image display apparatus 100 may acquire information about a first region related to a finger-touchable range (S510). The touch range of the user's finger may mean a touch range on a touch screen that may be touched by a finger of a hand used by a user to grip the medical image display apparatus 100. The medical image display apparatus 100 may acquire information about the first region that defines a touch range on a touch screen that may be touched by a finger of a hand used by a user to grip the medical image display apparatus 100.

The information about the first region that defines a finger-touchable range may include information about at least one of a maximum distance between a reference point and a point that may be touched by the user's finger (hereinafter, referred to as a ‘maximum finger-touchable distance’), a maximum angle formed at the intersection between a line connecting a reference point to a first point that may be touched by the user's finger and a line connecting the reference point to a second point that may be touched by the user's finger (hereinafter, referred to as a ‘maximum finger-touchable angle’), a maximum area of a finger-touchable region, and a shape of the region.

FIGS. 6 through 8 illustrate examples of pieces of information about a first region for defining a finger-touchable range.

Referring to FIG. 6, a medical image display apparatus 100 may acquire a maximum distance between a reference point x and a point y that may be touched by a finger of a user 5 as information about the first region.

The reference point may be predetermined as a default value or be set by the user 5. In some exemplary embodiments, the medical image display apparatus 100 may detect a position of a hand of the user 5 which is used to grip the medical image display apparatus 100 and determine the reference point based on the position of the hand of the user 5. The medical image display apparatus 100 may detect the position of the hand of the user 5 used to grip the medical image display apparatus 100 by using, for example, a sensor provided on a bezel surrounding a touch screen 110.

For example, the medical image display apparatus 100 may determine the reference point based on a position where the hand of the user 5 used to grip the medical image display apparatus 100 is in contact with the bezel, or a position where a finger touching the touch screen 110 of the medical image display apparatus 100 meets an edge of the touch screen 110.

Referring to FIG. 7, the medical image display apparatus 100 may acquire a maximum angle θ formed at the intersection between a line xy from a reference point x to a first point y that may be touched by the finger of the user 5 and a line xy′ from the reference point x to a second point y′ that may be touched by the finger of the user 5 as information about the first region.

Referring to FIG. 8, the medical image display apparatus 100 may acquire a maximum area s or a shape of a region 801 that may be touched by the finger of the user 5 as information about the first region.

The medical image display apparatus 100 may acquire information about the first region by receiving the information about the first region from the outside or analyzing a user input.

For example, the medical image display apparatus 100 may identify a user of the medical image display apparatus 100 and acquire information about a first region prestored for the identified user. To acquire information about the first region, the medical image display apparatus 100 may receive user identification (ID) information and read out information about a touch range corresponding to the received user ID information from a memory. The medical image display apparatus 100 may acquire the information about the first region from a memory included in the medical image display apparatus 100, a memory of an external device, and an external server. Methods of receiving user ID information will be described in greater detail below with reference to FIGS. 13 through 16.

As another example, the medical image display apparatus 100 may acquire information about the first region by analyzing a touch gesture received from a user. The medical image display apparatus 100 may display a guide image for guiding a touch gesture from the user and receive the touch gesture corresponding to the guide image from the user. The medical image display apparatus 100 may then acquire information about the first region by analyzing the received touch gesture. Methods of acquiring information about the first region based on a touch gesture from a user will be described in greater detail below with reference to FIGS. 17 through 24.

As another example, the medical image display apparatus 100 may receive information about the first region directly from the user. The medical image display apparatus 100 may display a UI for receiving information about the first region and acquire a user input received from the user as the information about the first region. For example, the medical image display apparatus 100 may receive from the user information about at least one of a maximum finger-touchable distance, a maximum finger-touchable angle, a maximum area of a finger-touchable region, and a shape of the region. A method of receiving information about the first region from the user will be described in greater detail below with reference to FIGS. 25 and 26.

According to an exemplary embodiment, the medical image display apparatus 100 may be temporarily fixed at a certain position or be carried by the user when it is used. For example, the medical image display apparatus 100 may be temporarily fixed at a certain position for use thereof by being attached to another device or mounted on a stationary object. If the medical image display apparatus 100 is held and moved by the user, the medical image display apparatus 100 may acquire information about a finger-touchable range and provide a UI suitable for the touch range.

For example, if the medical image display apparatus 100 is detached from a medical image acquisition apparatus for acquiring medical image data from an object, the medical image display apparatus 100 may acquire information about a first region.

As another example, the medical image display apparatus 100 may detect motion information of the medical image display apparatus 100. If it is determined, based on the motion information, that the medical image display apparatus 100 is moving, the medical image display apparatus 100 may acquire information about the first region. For example, the medical image display apparatus 100 may detect at least one of a speed, an acceleration, and a slope thereof and, if the detected value is greater than or equal to a threshold value thereof, the medical image display apparatus 100 may determine that the medical image display apparatus 100 is moving.

As another example, if the medical image display apparatus 100 senses a user's hand used to grip the medical image display apparatus 100, the medical image display apparatus 100 may acquire information about the first region. In this case, the medical image display apparatus 100 may detect the user's hand used to grip the medical image display apparatus 100 via a sensor disposed on the bezel surrounding the touch screen 110.

According to an exemplary embodiment, if a user holding the medical image display apparatus 100 is changed, the medical image display apparatus 100 may acquire information about a touch range of a new user's finger. The medical image display apparatus 100 may provide a UI suitable for the new user based on the newly acquired information. In some exemplary embodiments, if a position of a user's hand used to grip the medical image display apparatus 100 is changed, the medical image display apparatus 100 may acquire again information about a finger-touchable range. The medical image display apparatus 100 may provide, based on the newly acquired information, a UI suitable for a new position of the user's hand.

Referring back to FIG. 5, the medical image display apparatus 100 may select a UI corresponding to a size of the first region from among a plurality of UIs related to a medical image (S520).

The plurality of UIs related to a medical image may include at least one of a GUI for setting parameters related to the medical image, a GUI for controlling an external device or server connected to the medical image display apparatus 100, and a UI for displaying information about the medical image.

The medical image display apparatus 100 may select a UI corresponding to a size of the first region from among the plurality of UIs, based on a result of comparing the size of the first region with a threshold value. The threshold value may be predetermined as a default value or may be set by the user.

For example, the medical image display apparatus 100 may compare at least one of a maximum finger-touchable distance, a maximum finger-touchable angle, and a maximum area of a finger-touchable region, with a threshold value and select a UI based on a comparison result. Methods of selecting, by the medical image display apparatus 100, a UI corresponding to a size of the first region will be described in greater detail below with reference to FIGS. 27 and 28.

The medical image display apparatus 100 may perform a function selected by the user from among all functions provided by the medical image display apparatus 100 in relation to a medical image. The medical image display apparatus 100 may provide a UI that allows the user to select at least one function. Each of the plurality of UIs related to a medical image may include at least one icon that allows the user to select a different number of functions.

The medical image display apparatus 100 may select a number of functions corresponding to a size of the first region from among all functions related to a medical image, which are provided by the medical image display apparatus 100. The medical image display apparatus 100 may select, from among the plurality of UIs, a UI including at least one icon corresponding to the selected functions. For example, as the size of the first region increases, the medical image display apparatus 100 may select a UI including more functions.

According to an exemplary embodiment, the medical image display apparatus 100 may provide a plurality of UIs capable of receiving user inputs based on various touch gestures.

Examples of a user's touch gesture may include tap, touch and hold, double tap, drag, panning, flick, drag and drop, pinch, swipe, etc.

“Tap” may be performed by touching a screen with a finger or touch instrument (e.g., an electronic pen) and immediately lifting the finger or touch instrument off the screen without moving it around.

“Touch and hold” may occur when a user touches a screen with a finger or touch instrument (e.g., an electronic pen) and holds the touch input for a threshold time (e.g., 2 seconds) or longer. In other words, a time difference between a touch-in time point and a touch-out time point is greater than or equal to the threshold time (e. g., 2 seconds).

“Double tap” may occur when a user touches a screen with the user's finger or a touch instrument (e.g., a stylus) twice in less than a threshold time (e.g., 2 seconds).

“Drag” may occur when a user places a finger or touch instrument on a screen moves the finger or the touch tool to another location on the screen without lifting it from the screen. The drag gesture may be used to move an object or perform a pan gesture as described below.

“Panning” may be a gesture in which a user performs a drag without selecting an object. Because the panning gesture is performed without selecting a specific object, the panning may move a page in a screen or an object group in the page instead of moving an object in the page.

“Flick” may occur when a user performs a drag at a threshold speed (e.g., 100 pixels/s) or faster by using a finger or touch instrument. Drag and Flick gestures may be distinguished from each other based on whether the finger or the touch instrument moves at the threshold speed (e.g., 100 pixels/s) or higher.

“Drag and drop” may occur when a user drags an object to a certain location on a screen and drops the object thereon by using a finger or touch instrument.

“Pinch” may be a gesture where a user places two fingers on a screen and moves the two fingers in different directions without lifting the two fingers from the screen. The pinch gesture is used to zoom in an object or page (Pinch Open) or zoom out the object or page (Pinch Close). In this case, a zoom-in ratio or zoom-out ratio is determined according to a distance between the two fingers.

“Swipe” may be performed by touching an object on a screen with a finger or touch instrument and moving the finger or touch instrument in a certain direction by a certain distance.

A size of a region on a touch screen that a user may use to input a touch gesture varies depending on the type of touch gesture. For example, when the user inputs touch gestures involving moving a finger or touch instrument, such as drag, panning, flick, and swipe gestures, the user may use a greater region on a touch screen than when he or she inputs a tap, touch and hold, or double tap gesture. Thus, according to an exemplary embodiment, the medical image display apparatus 100 may provide a plurality of UIs configured to receive different touch gestures according to a size of a finger-touchable range.

The medical image display apparatus 100 may select a touch gesture corresponding to a size of the first region from among different types of touch gestures. The medical image display apparatus 100 may select a UI configured to receive the selected touch gesture from among a plurality of UIs. For example, if the size of the first region is greater than a threshold value, the medical image display apparatus 100 may select a first UI configured to receive at least one touch gesture among drag, panning, flick, and swipe gestures. Otherwise, if the size of the first region is less than or equal to the threshold value, the medical image display apparatus 100 may select a second UI configured to receive at least one touch gesture among tap, touch and hold, and double tap gestures.

In addition, a thickness of a finger, a strength of a finger touching the touch screen 110, or a posture of a finger touching the touch screen 110 may vary according to user. Thus, a contact area of a finger with the touch screen 110 when the finger touches the touch screen 110 (hereinafter, referred to as a ‘finger contact area’) may vary according to users. Furthermore, even for the same user, a finger contact area may vary according to, for example, which finger touches the touch screen 110, or a posture of a finger touching the touch screen 110.

For example, as a thickness of a finger touching the touch screen 110 increases, a finger contact area may increase. Furthermore, as a strength of a touch on the touch screen 110 increases, the finger contact area may increase. As a finger touching the touch screen 110 becomes more perpendicular to the touch screen 110, the finger contact area may decrease.

Thus, the medical image display apparatus 100 may display a UI by further taking into account a user's finger contact area. The medical image display apparatus 100 may select a UI including at least one icon having a size corresponding to a user's finger contact area from among a plurality of UIs. For example, as the user's finger contact area decreases, the medical image display apparatus 100 may select a UI including a smaller icon, as described in more detail below with reference to FIGS. 58 and 59.

According to an exemplary embodiment, the medical image display apparatus 100 may select one UI from among a plurality of UIs by further taking into account at least one of a direction in which the medical image display apparatus 100 displays content and a side of the medical image display apparatus 100 where a user's hand used to grip the medical image display apparatus 100 is located, as described in more detail below with reference to FIGS. 44 through 52.

The medical image display apparatus 100 may display the UI selected in operation S520 previously (S530).

The medical image display apparatus 100 may display the selected UI at a position determined based on a position of a user's hand or finger.

To ensure a medical image provided via the medical image display apparatus 100 may be used for diagnosis or treatment of a disease, the medical image has to be provided to the user without distortion. For example, if a UI is displayed to overlap a medical image, accuracy of diagnosis and treatment of a disease may be degraded. Thus, the medical image display apparatus 100 may change a position where the medical image is to be displayed so that a selected UI and the medical image do not overlap each other, based on a position where the selected UI is displayed.

According to various exemplary embodiments, to provide a UI suitable for a user who holds and uses the medical image display apparatus 100, if the medical image display apparatus 100 determines that the user is holding and using the medical image display apparatus 100, the medical image display apparatus 100 may acquire information about a finger-touchable range. In some exemplary embodiments, to provide a UI suitable for each user, if a posture of a user's hand used to grip the medical image display apparatus 100 or a user is changed, the medical image display apparatus 100 may acquire information about a finger-touchable range.

FIGS. 9A and 9B are diagrams for explaining a method of acquiring information about a first region when a medical image display apparatus 100 is detached from a medical image acquisition apparatus, according to an exemplary embodiment.

The medical image display apparatus 100 may analyze the swipe touch received from the user 5 and acquire, based on an analysis result, a maximum finger-touchable distance as information about a first region.

For example, based on the swipe touch, the medical image display apparatus 100 may determine a distance by which the entity 1801 moves as a maximum finger-touchable distance. In some exemplary embodiments, the medical image display apparatus 100 may determine a distance between a reference point and a point where a speed of the swipe touch corresponds to a threshold speed as a maximum finger-touchable distance. In this case, the reference point may correspond to an initial position at which the entity 1801 is displayed.

FIG. 19 is a flowchart of a method of acquiring, by the medical image display apparatus 100, a maximum finger-touchable distance based on a speed at which a swipe touch moves (which may be referred to as a “swipe touch speed” or a “speed of swipe touch”), according to an exemplary embodiment.

The medical image display apparatus 100 may compare a speed of swipe touch received from the user with a threshold speed and determine, based on a comparison result, a distance between a “reference point” and a “point where the speed of the swipe touch corresponds to the threshold speed” as a maximum finger-touchable distance.

As shown in FIG. 21, the medical image display apparatus 100 may determine a distance between a first point x where a speed of a swipe touch for moving the entity 1801 in a first direction corresponds to a threshold speed and a second point y where a speed of a swipe touch for moving the entity 1801 in a second direction corresponds to a threshold speed as a maximum finger-touchable distance. The first direction may be opposite to the second direction. The medical image display apparatus 100 may acquire the maximum finger-touchable distance as the information about the first region.

FIG. 22A illustrates an example of a guide image displayed by a medical image display apparatus 100 to guide a touch gesture from a user 5, according to an exemplary embodiment.

The medical image display apparatus 100 may display a guide image for guiding an input of a predetermined touch gesture by the user 5. For example, the medical image display apparatus 100 may display a guide image for guiding an input of a touch gesture in which the user 5 touches a touch screen 110 with a finger and moves the finger to another location without lifting the finger off the touch screen 110.

Referring to FIG. 22A, the medical image display apparatus 100 may display an entity 2201 for guiding a touch gesture in which the user 5 touches the entity 2201 with a finger and moves the finger to another location along a certain path 2203 without lifting the finger. The medical image display apparatus 100 may receive a touch gesture involving moving the entity 2201 along the path 2203 indicated by an arrow.

The medical image display apparatus 100 may analyze the touch gesture received from the user 5 and acquire at least one of a maximum finger-touchable angle, a maximum area of a finger-touchable region, and a shape of the region as information about a first region.

For example, the medical image display apparatus 100 may extract an arc from a path along which the entity 2201 has moved based on the touch gesture and determine a central angle of a circular sector corresponding to the extracted arc as a maximum finger-touchable angle. In this case, the medical image display apparatus 100 may extract an arc of a circular sector with a reference point at a center from the path.

In some exemplary embodiments, the medical image display apparatus 100 may determine an area of a region, which includes a path along which the entity 2201 has moved based on the touch gesture as a contour, as a maximum area of a finger-touchable region.

In some exemplary embodiments, the medical image display apparatus 100 may acquire a shape of a region including a path along which the entity 2201 has moved based on the touch gesture as a contour as information about the first region.

The medical image display apparatus 100 may determine whether a touch gesture received from the user is a touch gesture corresponding to a guide image. The medical image display apparatus 100 may compare a path of movement of a finger determined based on the touch gesture received from the user with a predetermined path indicated in the guide image and determine whether the received touch gesture is the touch gesture corresponding to the guide image based on a comparison result. If the received touch gesture is determined to be the touch gesture corresponding to the guide image, the medical image display apparatus 100 may determine a finger-touchable range by analyzing the received touch gesture. Otherwise, if the received touch gesture is not determined to be the touch gesture corresponding to the guide image, the medical image display apparatus 100 may display a guide image for guiding re-input of a touch gesture by the user.

FIG. 22B is a flowchart of a method of determining, by the medical image display apparatus 100, a finger-touchable range by comparing a guide image with a touch gesture received from a user, according to an exemplary embodiment.

The medical image display apparatus 100 may display a guide image for guiding a touch gesture from a user (S2210). For example, as shown in FIG. 22A, the guide image may include the entity 2201 and the path 2203 to elicit a touch gesture involving moving the entity 2201 along the path 2203

The medical image display apparatus 100 may receive a touch gesture from the user (S2220). For example, the medical image display apparatus 100 may receive a touch gesture in which the user touches the touch screen 110 with a finger and moves the finger to another location along a certain path included in the guide image while still touching the touch screen 110

The medical image display apparatus 100 may compare an error of the touch gesture received from the user to a threshold value (S2230). The medical image display apparatus 100 may determine whether the received touch gesture is a touch gesture corresponding to the guide image based on a comparison result.

The error of the touch gesture received from the user may mean a difference between a path of movement of a finger determined based on the received touch gesture and a predetermined path included in the guide image. For example, the error of the touch gesture received from the user may be determined based on a degree of similarity between the path of movement of the finger and the predetermined path included in the guide image.

If the error of the received touch gesture is greater than or equal to the threshold value, the medical image display apparatus 100 may determine that the received touch gesture is not a touch gesture corresponding to the guide image. In this case, the medical image display apparatus 100 may return to operation S2210 and receive again a touch gesture from the user. The medical image display apparatus 100 may repeat operations S2210 through S2230 until receiving a touch gesture corresponding to the guide image.

If the error of the received touch gesture is less than the threshold value, the medical image display apparatus 100 may determine a finger-touchable range by analyzing the received touch gesture (S2240). The medical image display apparatus 100 may analyze the received touch gesture and acquire, based on an analysis result, at least one of a maximum finger-touchable angle, a maximum area of a finger-touchable region, and a shape of the region as information about a first region.

Referring to FIG. 23, the medical image display apparatus 100 may analyze a touch gesture in which the user 5 touches an entity 2201 and moves the entity 2201 to another location while maintaining a touch on the entity 2201, and may acquire information about a first region. The medical image display apparatus 100 may extract an arc yy′ from a path along which the entity 2201 has moved and determine a central angle θ of a circular sector corresponding to the arc yy′ as a maximum finger-touchable angle.

FIG. 24 is a diagram for explaining a method of acquiring, by a medical image display apparatus 100, a maximum area of a region that may be touched by a finger of a user 5 as information about a first region, according to an exemplary embodiment.

As shown in FIG. 24, the medical image display apparatus 100 may analyze a touch gesture in which the user 5 touches an entity 2201 and moves the entity 2201 to another location while still touching the entity 2201 and acquire information about a first region based on an analysis result. The medical image display apparatus 100 may determine a region 2401 including a path along which the entity 2201 has moved as a contour and then an area S of the determined region 2401 as a maximum area of a region that may be touched by a finger of the user 5.

In addition, according to an exemplary embodiment, the medical image display apparatus 100 may receive information about the first region directly from a user. In detail, the medical image display apparatus 100 may display a UI for receiving information about the first region and acquire a user input received from the user as the information about the first region.

FIG. 25 is a flowchart of a method of acquiring, by the medical image display apparatus 100, a user input as information about a first region, according to an exemplary embodiment.

The medical image display apparatus 100 may display a UI for receiving information about a first region (S2510).

In detail, when it is determined that a user is holding and using the medical image display apparatus 100 and if a posture of a hand of the user used to grip the medical image display apparatus 100 or the user himself/herself is changed, the medical image display apparatus 100 may receive a UI for receiving information about the first region.

In some exemplary embodiments, the medical image display apparatus 100 may display a UI for receiving information about the first region based on a user input.

The medical image display apparatus 100 may receive a user input as the information about the first region (S2520). For example, the medical image display apparatus 10 may receive from the user at least one of a length of a user's finger, a maximum finger-touchable distance in a transverse direction, a maximum finger-touchable distance in a longitudinal direction, and a maximum finger-touchable angle.

The medical image display apparatus 100 may map the information about the first region to ID information of the user storage (S2530).

The medical image display apparatus 100 may receive ID information of a first user from the first user. In some exemplary embodiments, the medical image display apparatus 100 may receive ID information of the first user via a predetermined operation performed by the first user. For example, the predetermined operation may include bringing an ID card containing the ID information of the first user close to or into contact with the medical image display apparatus 100, or otherwise providing the ID card, or entering a first user's name or ID via the medical image display apparatus 100, etc.

FIG. 26 illustrates an example of a UI for receiving information about a first region and which is displayed by a medical image display apparatus 100, according to an exemplary embodiment.

Referring to FIG. 26, the medical image display apparatus 100 may receive information about a first region for defining a finger-touchable range from the user. The medical image display apparatus 100 may receive the information about the first region based on a user input for selecting at least one key included in a keypad 2603 displayed on a touch screen 110. The information about the first region input by the user via the keypad 2603 may be displayed in an information input region 2601.

As shown in FIG. 26, the medical image display apparatus 100 may receive from the user at least one of a length of a finger, a maximum finger-touchable distance r in a transverse direction, a maximum finger-touchable distance in a longitudinal direction, and a maximum finger-touchable angle.

Exemplary methods of acquiring, by the medical image display apparatus 100, information about the first region according to various exemplary embodiments have been described above with reference to FIGS. 9A through 26. According to various exemplary embodiments, after acquiring information about the first region, the medical image display apparatus 100 may select a UI corresponding to a size of the first region based on the acquired information about the first region. For example, the medical image display apparatus 100 may select a UI corresponding to a size of the first region from among a plurality of UIs, based on a result of comparing the size of the first region to at least one threshold value.

By selecting a UI corresponding to a size of the first region, the medical image display apparatus 100 may provide a user with a UI suitable for a finger-touchable range. As the touch range of the user's finger increases (i.e., as the first region increases in size), the medical image display apparatus 100 may select a UI that occupies a greater area on the touch screen 110

Furthermore, the medical image display apparatus 100 may select a UI configured to receive a touch gesture suitable according to a size of the first region, from among a plurality of UIs.

A size of a region on a touch screen that the user may use to input a touch gesture may vary depending on the type of a touch gesture. Thus, an area on the touch screen 110 occupied by each of a plurality of UIs may vary according to which type of touch gesture a UI is configured to receive.

Thus, the medical image display apparatus 100 may select a type of touch gesture corresponding to a size of the first region from among different types of touch gestures and then a UI configured to receive the selected touch gesture.

For example, when the user inputs touch gestures involving moving a finger or touch instrument, such as drag, panning, flick, and swipe touch gestures, the user may use a greater region on a touch screen than when he or she inputs a tap, touch and hold, or double tap touch gesture. Thus, if the first region has a large size, the medical image display apparatus 100 may select a UI configured to receive at least one of drag, panning, flick, and swipe touch gestures. Otherwise, if the first region has a small size, the medical image display apparatus 100 may select a UI configured to receive at least one of tap, touch and hold, and double tap touch gestures.

Furthermore, the medical image display apparatus 100 may select a UI having an operation depth suitable according to a size of the first region from among a plurality of UIs. An operation depth of a UI may mean a range of functions of the medical image display apparatus 100 that may be used by the user via the UI. As an operation depth of a UI decreases, the user may use fewer functions of the medical image display apparatus 100. As an operation depth of a UI increases, the user may use more functions of the medical image display apparatus 100.

An area on the touch screen 110 occupied by each of a plurality of UIs may vary according to the number of functions corresponding to icons included in a UI. Thus, as a size of the first region increases, the medical image display apparatus 100 may select a UI providing more functions. As the size of the first region decreases, the medical image display apparatus 100 may select a UI providing fewer functions.

The number of functions selected by the medical image display apparatus 100 from among all functions provided by the medical image display apparatus 100 in relation to a medical image, may correspond to a size of the first region. The medical image display apparatus 100 may then select a UI including at least one icon corresponding to the selected functions.

FIG. 27 is a flowchart of a method of selecting, by the medical image display apparatus 100, a UI based on a result of comparing a size of a first region with a threshold value, according to an exemplary embodiment.

Operation S2705 illustrated in FIG. 27 may correspond to operation S510 illustrated in FIG. 5 and operations S2710, S2720, S2731, S2733, and S2735 may, in some exemplary embodiments, be included in operation S520 illustrated in FIG. 5. Thus, the same descriptions as provided above with respect to FIG. 5 will be omitted here.

The medical image display apparatus 100 may acquire information about a first region (S2705).

The medical image display apparatus 100 may acquire the information about the first region from a memory included in the medical image display apparatus 100, a memory of an external device, or an external server. In some exemplary embodiments, the medical image display apparatus 100 may acquire the information about the first region by analyzing a touch gesture received from the user in response to a guide image. In addition, the medical image display apparatus 100 may receive the information about the first region directly from the user.

The medical image display apparatus 100 may compare a size of the first region to a first threshold value (S2710). The first threshold value may be predetermined as a default value or may be set by the user. For example, the first threshold value may be a value corresponding to a size of a first UI.

If the size of the first region is greater than the first threshold value, the medical image display apparatus 100 may select a first UI from among a plurality of UIs (S2731).

If the size of the first region is less than or equal to the first threshold value, the medical image display apparatus 100 may compare the size of the first region to a second threshold value (S2720). In some exemplary embodiments, the second threshold value may be less than the first threshold value. The second threshold value may be predetermined as a default value or may be set by the user. For example, the second threshold value may be a value corresponding to a size of a second UI.

If the size of the first region is greater than the second threshold value, the medical image display apparatus 100 may select a second UI from among the plurality of UIs (S2733). Otherwise, if the size of the first region is less than or equal to the second threshold value, the medical image display apparatus 100 may select a third UI from among the plurality of UIs (S2735).

The medical image display apparatus 100 may display a selected UI within a touch range of the user's finger.

FIG. 28 illustrates examples of a plurality of first through third UIs 2811, 2821, and 2831 selected by a medical image display apparatus 100 based on a result of comparing a size of a first region with a threshold value, according to an exemplary embodiment.

Referring to FIG. 28, the medical image display apparatus 100 acquires a maximum finger-touchable distance as information about the first region. In other words, the medical image display apparatus 100 may acquire the maximum finger-touchable distance as a value indicative of a size of the first region.

The medical image display apparatus 100 may compare the maximum finger-touchable distance to a first threshold value of 5 cm. If the maximum finger-touchable distance is greater than 5 cm, the medical image display apparatus 100 may select the first UI 2811 from among the first through third UIs 2811, 2821, and 2831. As shown in a portion 2810, when the first UI 2811 is selected, the medical image display apparatus 100 may display the selected first UI 2811 on a touch screen 110.

If the maximum finger-touchable distance is less than or equal to 5 cm, the medical image display apparatus 100 may compare the maximum finger-touchable distance to a second threshold value of 3 cm. If the maximum finger-touchable distance is less than or equal to 5 cm but is greater than 3 cm, the medical image display apparatus 100 may select the second UI 2821 from among the first through third UIs 2811, 2821, and 2831. As shown in a portion 2820, when the second UI 2821 is selected, the medical image display apparatus 100 may display the selected second UI 2821 on the touch screen 110.

If the maximum finger-touchable distance is less than or equal to 3 cm, the medical image display apparatus 100 may select the third UI 2832 from among the first through third UIs 2811, 2821, and 2831. As shown in a portion 2830, when the third UI 2831 is selected, the medical image display apparatus 100 may display the selected third UI 2831 on the touch screen 110.

As shown in FIG. 28, the medical image display apparatus 100 may select a type of touch gesture corresponding to the size of the first region from among different types of touch gestures and then a UI configured to receive the selected touch gesture.

For example, the first UI 2811 may be configured to receive a swipe touch and a flick touch, the second UI 2821 may be configured to receive a tap touch, touch and hold, and a flick touch, and the third UI 2831 may be configured to receive a tap touch and touch and hold.

To detect a swipe touch, the medical image display apparatus 100 may require a greater area on the touch screen 110 than to detect a flick touch, a tap touch, and touch and hold. Thus, if the first region has a large size, the medical image display apparatus 100 may select the first UI 2811 configured to receive a swipe touch and a flick touch. On the other hand, if the first region has a very small size, the medical image display apparatus 100 may select the third UI 2831 configured to receive only a tap touch and a touch and hold gesture.

Furthermore, as shown in FIG. 28, as the size of the first region increases, the medical image display apparatus 100 may select a UI providing more functions.

For example, the first UI 2811 may include icons corresponding to four (4) functions performed by the medical image display apparatus 100. In detail, the first UI 2811 may include icons corresponding to a function of adjusting frequency of an ultrasound signal transmitted by an ultrasound probe of the ultrasound diagnosis device 11 of FIG. 1, a function of adjusting a depth of penetration of an ultrasound signal, a function of adjusting intensity of an ultrasound signal, and a function of changing an operating mode of the ultrasound diagnosis device 11 from a live mode to a freeze mode.

The second UI 2821 may include icons corresponding to three (3) functions, i.e., a function of adjusting intensity of an ultrasound signal, a function of changing an operating mode of the ultrasound diagnosis device 11 from a live mode to a freeze mode, and a function of capturing an ultrasound image.

The third UI 2831 may include icons corresponding to two (2) functions, i.e., a function of changing an operating mode of the ultrasound diagnosis device 11 from a live mode to a freeze mode and a function of changing the operating mode from a freeze mode to a live mode.

When the first region has a large size, the medical image display apparatus 100 may select the first UI 2811 including icons corresponding to a large number of functions. Thus, if the first region is large in size, the user may control the medical image display apparatus 100 to perform a large number of functions by selecting the icons included in the first UI 2811. On the other hand, when the first region has a small size, the medical image display apparatus 100 may select the third UI 2831 including icons corresponding to a small number of functions. Thus, if the first region is small in size, the user may control the medical image display apparatus 100 to perform only a limited number of functions by selecting the icons included in the third UI 2831.

UIs that may be provided by the medical image display apparatus 100 according to various exemplary embodiments will now be described in detail with reference to FIGS. 29 through 43.

The medical image display apparatus 100 may provide a UI for adjusting a parameter related to a medical image. The parameter related to the medical image may include at least one piece of information from among pieces of information about numerical values that are set with respect to an operation of acquiring the medical image to be displayed via the medical image display apparatus 100, numerical values that are set with respect to an operation of displaying the acquired medical image, and numerical values related to an object depicted in the medical image.

FIG. 29 is a flowchart of a method of providing, by the medical image display apparatus 100, a UI for adjusting a parameter according to an exemplary embodiment.

The medical image display apparatus 100 may display a first UI (S2910).

As illustrated in FIG. 5, the medical image display apparatus 100 may select a first UI corresponding to a size of a first region from among a plurality of UIs and display the selected first UI. The medical image display apparatus 100 may display the first UI within the first region determined as a finger-touchable region.

The first UI may include a plurality of icons that are selectable by a user. An icon may be a character or picture to represent a command for performing a function provided by the medical image display apparatus 100. For example, the first UI may include a plurality of icons representing commands for performing at least one of a function of setting a parameter related to a medical image, a function of controlling an external device or server connected to the medical image display apparatus 100, and a function of inputting information about the medical image.

The medical image display apparatus 100 may receive a touch gesture for selecting a first icon from among a plurality of icons included in the first UI (S2920).

At least one of the plurality of icons included in the first UI may represent a command for performing a function of adjusting at least one parameter related to a medical image. The plurality of icons may include the first icon related to a function of adjusting a parameter related to the medical image. To adjust the parameter, the user may input the touch gesture for selecting the first icon from among the plurality of icons.

When a predetermined touch gesture with respect to the first icon is received, the medical image display apparatus 100 may determine that a touch gesture for selecting the first icon has been received. For example, when a certain type of touch gesture is input to a region of the touch screen 110 corresponding to the first icon, the medical image display apparatus 100 may determine that a touch gesture for selecting the first icon has been received.

A type of touch gesture that the medical image display apparatus 100 is to receive from the user in order to select at least one icon from among a plurality of icons may be predetermined as a default value or may be set by the user. In some exemplary embodiments, the medical image display apparatus 100 may select a UI that is configured to receive a specific touch gesture, based on the size of the first region.

The medical image display apparatus 100 may display a second UI for adjusting a parameter corresponding to the first icon in a first region (S2930).

When the touch gesture for selecting the first icon from among the plurality of icons included in the first UI is received, the medical image display apparatus 100 may load the second UI on a touch screen. In the first region, the medical image display apparatus 100 may display the second UI instead of the first UI. The second UI may be a submenu under the first UI.

The user may adjust the parameter corresponding to the first icon via the second UI. The second UI may include a plurality of sections respectively corresponding to values that increase by a certain value along a certain direction.

The medical image display apparatus 100 may receive a touch gesture involving movement of a user's finger from a first section to a second section among a plurality of sections included in the second UI (S2940).

The second UI may include a plurality of sections respectively corresponding to a plurality of values of the parameter corresponding to the first icon. The number of sections to be included in the second UI may be predetermined as a default value or may be set by the user. As the second UI includes more sections, the user may adjust a parameter more precisely.

To set the parameter corresponding to the first icon to a certain value, the user may input a touch gesture involving moving, for example, a user's finger, to a section corresponding to the certain value. For example, the medical image display apparatus 100 may receive at least one of drag, panning, and swipe touches involving touching the first section with the user's finger and moving the user's finger to the second section.

When the touch gesture involving movement of the user's finger from the first section to the second section is received, the medical image display apparatus 100 may change the parameter corresponding to the first icon from a first value corresponding to the first section to a second value corresponding to the second section (S2950).

FIG. 30 illustrates an example of UIs 3011 and 3021 provided by a medical image display apparatus 100 according to an exemplary embodiment.

As shown in a portion 3010, the medical image display apparatus 100 may display a medical image 3013 and the UI 3011 related to the medical image 3013. The UI 3011 may include a plurality of icons 3011-1 through 3011-4, i.e., an icon 3011-1 related to a function of adjusting a frequency of an ultrasound signal, an icon 3011-2 related to a function of adjusting a depth of penetration of an ultrasound signal, an icon 3011-3 related to a function of adjusting intensity of an ultrasound signal, and an icon 3011-4 related to a function of changing an operating mode of the ultrasound diagnosis device 11 from a live mode to a freeze mode. To adjust a parameter related to the medical image 3013, the user may input a touch gesture for selecting at least one of the plurality of icons 3011-1 through 3011-4.

To adjust a depth parameter related to a depth of penetration of an ultrasound signal, the user may select the icon 3011-2. When the medical image display apparatus 100 receives a swipe touch involving movement of a user's finger from a certain region in the UI 3011 into a region where the icon 3011-2 is displayed and a flick touch involving movement of the user's finger from the region where the icon 3011-2 is displayed outside a region where the UI 3011 is displayed, the medical image display apparatus 100 may determine that the touch gesture for selecting the icon 3011-2 has been received. An arrow in the portion 3010 represents the user's touch gesture for selecting the icon 3011-2.

As shown in a portion 3020, when the icon 3011-2 is selected, the medical image display apparatus 100 may display the UI 3021 for adjusting a depth parameter corresponding to the icon 3011-2.

As shown in the portion 3020, the UI 3021 may include five (5) sections 3021-1 through 3021-5 respectively corresponding to a plurality of values of the depth parameter corresponding to the selected icon 3011-2. The five sections 3021-1 through 3021-5 included in the UI 3021 may respectively correspond to the values of the depth parameter representing deeper penetration of an ultrasound signal, from the section 3021-1 towards the section 3021-5.

To set the depth parameter to a value corresponding to the section 3021-2, the user may select the section 3021-2. When the medical image display apparatus 100 receives a swipe touch involving movement of the user's finger from the section 3021-1 to the section 3021-2 in the UI 3021, the medical image display apparatus 100 may determine that a touch gesture for selecting the section 3021-2 has been received. An arrow in the portion 3020 represents a user's touch gesture for selecting the section 3021-2.

The medical image display apparatus 100 may change the depth parameter from a value corresponding to the section 3021-1 to a value corresponding to the section 3021-2.

The medical image display apparatus 100 may provide, for example, a moving image as a medical image. For example, the medical image display apparatus 100 may display a plurality of frames still images consecutively acquired from a moving object over time or a plurality of frames (still images) consecutively acquired from an object at a position that has changed over time.

When the user observes an object based on a moving image, it may be difficult to precisely observe cells, tissues, or organs that constitute the object, compared to observing the object based on a still image. Thus, a user provided with a moving image by the medical image display apparatus 100 may desire to store a still image of the object acquired at a certain time point for later use in diagnosis or treatment of a disease. To store the still image of the object acquired at the certain time point, the medical image display apparatus 100 may provide a UI related to a function of capturing a medical image.

FIG. 31 is a flowchart of a method of providing, by the medical image display apparatus 100, a UI for capturing a medical image according to an exemplary embodiment.

When the tap touch with respect to the icon 4203 is received, the medical image display apparatus 100 may determine that a command for capturing a medical image has been received from the user.

As shown in a portion 4320, when the tap touch with respect to the icon 4203 is received, the medical image display apparatus 100 may further display reduced versions 4225 of the ultrasound still image 4223. Furthermore, the medical image display apparatus 100 may store the ultrasound still image 4223 in a memory.

According to an exemplary embodiment, as shown in FIGS. 42 and 43, when a user's touch range is very narrow, the medical image display apparatus 100 may be configured to support a UI providing only a minimum number of functions, thereby allowing the user to conveniently use the medical image display apparatus 100.

In addition, as shown in FIG. 44, a finger-touchable range and the degree of ease of use of the medical image display apparatus 100 by the user may vary depending on a direction in which the medical image display apparatus 100 displays content and a position of a user's hand used to grip the medical image display apparatus 100.

FIG. 44 shows an example where the medical image display apparatus 100 is a device having a rectangular or semi-rectangular shape including a short first side 4401 and a long second side 4402.

As shown in a portion 4410, when the medical image display apparatus 100 displays content in a longitudinal direction and a user 5 grips the second side 4402 of the medical image display apparatus 100, a touch range of a finger of the user 5 may be relatively wide.

On the other hand, as shown in a portion 4420, when the medical image display apparatus 100 displays content in a transverse direction and the user 5 grips the second side 4402 of the medical image display apparatus 100, a touch range of a finger of the user 5 may become relatively narrow.

As shown in a portion 4430, the user 5 grips the medical image display apparatus 100 in a stable posture. However, if the user 5 grips the medical image display apparatus 100 in such a posture as shown in the portion 4430, the user may have difficulty in using the medical image display apparatus 100 by touching the touch screen (110 of FIG. 3) since it may be hard to move his or her fingers.

Maintaining a posture as shown in a portion 440 while gripping the medical image display apparatus 100 may be impractical because the posture places extreme loads on a wrist of the user 5.

Thus, according to an exemplary embodiment, the medical image display apparatus 100 may select a UI from among a plurality of UIs by further taking into account at least one of a direction in which the medical image display apparatus 100 displays content and a side of the medical image display apparatus 100 where a user's hand used to grip the medical image display apparatus 100 is located, thereby providing improved user convenience.

FIG. 45 is a flowchart of a method of providing a UI corresponding to a direction in which the medical image display apparatus 100 displays content according to an exemplary embodiment.

Referring to FIG. 45, the medical image display apparatus 100 may acquire information about a direction in which the medical image display apparatus 100 displays content (S4510).

The medical image display apparatus 100 may acquire information about whether the medical image display apparatus 100 displays content in a longitudinal or transverse direction.

For example, the medical image display apparatus 100 may be a device having a rectangular or semi-rectangular shape including a short first side and a long second side. Displaying content in the longitudinal direction may mean arranging and displaying the content along the second side. Displaying content in the transverse direction may mean arranging and displaying the content along the first side.

The medical image display apparatus 100 may detect a slope thereof by using a sensing unit disposed therein. For example, the medical image display apparatus 100 may acquire motion information of the medical image display apparatus by using a magnetic sensor, an acceleration sensor, or a gyroscope sensor provided therein.

The medical image display apparatus 100 may determine whether to display content in a longitudinal or transverse direction according to a slope of the medical image display apparatus 100. Thus, the medical image display apparatus 100 may acquire information about the direction in which the medical image display apparatus 100 displays content, based on information about the slope of the medical image display apparatus 100.

The medical image display apparatus 100 may select a UI corresponding to the direction in which the medical image display apparatus 100 displays content, from among a plurality of UIs related to a medical image (S4520).

The plurality of UIs related to a medical image may include at least one of a GUI for setting a parameter related to a medical image, a GUI for controlling an external device or server connected to the medical image display apparatus 100, and a UI for displaying information about the medical image.

The medical image display apparatus 100 may display the UI selected in operation S4520 (S4530).

The medical image display apparatus 100 may display the selected UI at a position determined based on a position of a user's hand or finger.

FIG. 46 illustrates examples of a plurality of first and second UIs 4611 and 4621 provided based on a direction in which a medical image display apparatus 100 displays content, according to an exemplary embodiment.

Referring to FIG. 46, the user grips a second side of the medical image display apparatus 100.

When the medical image display apparatus 100 displays content in a longitudinal direction, the medical image display apparatus 100 may select the first UI 4611 from among the first and second UIs 4611 and 4621. As shown in a portion 4610, when the first UI 4611 is selected, the medical image display apparatus 100 may display the selected first UI 4611 on a touch screen 110.

When the medical image display apparatus 100 displays content in a transverse direction, the medical image display apparatus 100 may select the second UI 4621 from among the first and second UIs 4611 and 4621. As shown in a portion 4620, when the second UI 4621 is selected, the medical image display apparatus 100 may display the selected second UI 4621 on the touch screen 110.

As shown in FIG. 46, the medical image display apparatus 100 may select UIs having different sizes based on a direction in which the medical image display apparatus 100 displays content.

When the user grips the second side of the medical image display apparatus 100 that displays content in the longitudinal direction, a finger-touchable range may be greater than when the user grips the second side of the medical image display apparatus 100 that displays content in the transverse direction.

When the medical image display apparatus 100 displays content in the longitudinal direction, the medical image display apparatus 100 may select the first UI 4611, which may have a larger size from among the first and second UIs 4611 and 4621. When the medical image display apparatus 100 displays the content in the transverse direction, the medical image display apparatus 100 may select the second UI 4621 having a smaller size from among the first and second UIs 4611 and 4621.

Furthermore, as shown in FIG. 46, the medical image display apparatus 100 may select a UI configured to receive a different type of touch gesture based on a direction in which the medical image display apparatus 100 displays content.

The medical image display apparatus 100 may select from among different types of touch gestures a type of touch gesture corresponding to a direction in which the medical image display apparatus 100 displays content and select a UI configured to receive the selected touch gesture.

For example, a greater region on the touch screen 110 may be required for the medical image display apparatus 100 to detect a swipe touch and a flick touch than to detect a tap touch and a touch and hold gesture.

Thus, when a finger-touchable range increases according to a direction in which the medical image display apparatus 100 displays content, the medical image display apparatus 100 may select the first UI 4611 configured to receive a swipe touch and a flick touch. When a finger-touchable range decreases according to a direction in which the medical image display apparatus 100 displays the content, the medical image display apparatus 100 may select the second UI 4621, which may be configured to receive only a tap touch and a touch and hold gesture.

Furthermore, as shown in FIG. 46, the medical image display apparatus 100 may select UIs that provide a different number of functions based on a direction in which the medical image display apparatus 100 displays content.

The first UI 4611 may be a UI including icons corresponding to a function of adjusting a frequency of an ultrasound signal, a function of adjusting a depth of penetration of an ultrasound signal, and a function of changing an operating mode.

The second UI 4621 may be a UI including icons corresponding to a function of changing an operating mode and a function of capturing a medical image.

Thus, when a finger-touchable range increases according to a direction in which the medical image display apparatus 100 displays content, the medical image display apparatus 100 may select the first UI 4611 providing a large number of functions. When a finger-touchable range decreases according to a direction in which the medical image display apparatus 100 displays the content, the medical image display apparatus 100 may select the second UI 4621 providing a small number of functions.

In addition, the medical image display apparatus 100 may provide a UI by further taking into account a size of a finger-touchable range as well as a direction in which the medical image display apparatus 100 displays content.

To ensure a medical image provided via the medical image display apparatus 100 may be used for diagnosis or treatment of a disease, the medical image has to be provided to the user without distortion. For example, if a UI is displayed to overlap a medical image, accuracy of diagnosis and treatment of a disease may be degraded. Thus, the medical image display apparatus 100 may change a position where the medical image is to be displayed so that a selected UI and the medical image does not overlap each other, based on a position where the selected UI is displayed.

FIG. 53 is a flowchart of a method of displaying, by the medical image display apparatus 100, a UI based on a position of user's touch according to an exemplary embodiment.

Because operations S5310, S5320, and S5330 may be included in operation S530 illustrated in FIG. 5, the same descriptions as provided above with respect to FIG. 5 will be omitted here.

The medical image display apparatus 100 may detect a user's touch on a touch screen (S5310).

The medical image display apparatus 100 may display a UI at a position determined based on a position of user's touch (S5320).

As illustrated in FIG. 5, the medical image display apparatus 100 may select a UI corresponding to a size of a first region from among a plurality of UIs and display the selected UI at the determined position.

As shown in a portion 5410 of FIG. 54, the medical image display apparatus 100 may display a UI 5411 at a position of user's touch where the user's touch is detected. As shown in a portion 5420, when the position of user's touch changes, the medical image display apparatus 100 may display the UI 5411 at the changed position of user's touch.

Based on the position where the UI is displayed, the medical image display apparatus 100 may change a position where a medical image is to be displayed so that the medical image and the UI do not overlap each other (S5330).

Referring to FIG. 55, as shown in a portion 5510, the medical image display apparatus 100 may display a medical image 3013 based on a position where a UI 5511 is displayed, so that the medical image 3013 and the UI 5511 do not overlap each other. As shown in a portion 5520, when the position where the UI 5511 is displayed changes, the medical image display apparatus 100 may change a position where the medical image 3013 is to be displayed so that the medical image 3013 and the UI 5511 do not overlap each other.

When a user holding the medical image display apparatus 100 changes, a finger-touchable range may vary accordingly.

Thus, to provide a UI suitable for each user, the medical image display apparatus 100 may provide a UI having a different size according to a size of a finger-touchable range.

FIG. 56 is a flowchart of a method of providing, by the medical image display apparatus 100, UIs having sizes that differ according to users, according to an exemplary embodiment;

The medical image display apparatus 100 may display a UI having a first size corresponding to a first user (S5610).

The medical image display apparatus 100 may acquire information about a touch range of a finger of the first user from a memory included therein, a memory of an external device, or an external server. In some exemplary embodiments, the medical image display apparatus 100 may acquire the information about the touch range of the finger of the first user by analyzing a touch gesture received from the first user in response to a guide image. In addition, the medical image display apparatus 100 may receive the information about the touch range of the finger of the first user directly from the first user.

The medical image display apparatus 100 may display the UI having the first size corresponding to the touch range of the finger of the first user based on the information about the touch range. For example, the medical image display apparatus 100 may display a UI having a size that is less than or equal to the touch range of the finger of the first user.

The medical image display apparatus 100 may detect that a user gripping the medical image display apparatus 100 has changed from the first user to a second user (S5620).

For example, the medical image display apparatus 100 may detect whether a position of a user's hand used to grip the medical image display apparatus 100 has changed by using a sensing unit provided in the medical image display apparatus 100.

If the position of the user's hand used to grip the medical image display apparatus 100 has changed, the medical image display apparatus 100 may determine that the user holding the medical image display apparatus 100 has changed. If the user holding the medical image display apparatus 100 has changed, the medical image display apparatus 100 may display a GUI for receiving ID information of a new user.

The medical image display apparatus 100 may acquire information about a touch range of a finger of the second user (S5630).

The medical image display apparatus 100 may acquire the information about the touch range of the finger of the second user from a memory included therein, a memory of an external device, or an external server. In some exemplary embodiments, the medical image display apparatus 100 may acquire the information about the touch range of the finger of the second user by analyzing a touch gesture received from the second user in response to a guide image. In addition, the medical image display apparatus 100 may receive the information about the touch range of the finger of the second user directly from the second user.

The medical image display apparatus 100 may display a UI having a second size corresponding to the touch range of the finger of the second user (S5640).

Based on the touch range of the finger of the second user, the medical image display apparatus 100 may display the UI having the second size corresponding to the touch range. For example, the medical image display apparatus 100 may display a UI having a size that is less than or equal to the touch range of the finger of the second user.

FIG. 57 illustrates examples of UIs 5711 and 5721 having varying sizes corresponding to users according to an exemplary embodiment.

As shown in FIG. 57, different users 5-1 and 5-2 may have hands of varying sizes. For example, user 5-1 may have a hand that can be represented by hand 5710, and user 5-2 may have a hand that can be represented by hand 5720, which can be smaller than hand 5710. Thus, when a user holding the medical image display apparatus 100 changes from the user 5-1 to the user 5-2, a touch range of a finger of the user 5-1 may be changed accordingly. The medical image display apparatus 100 may provide a UI having a different size according to a finger-touchable range.

As shown in a portion 5710 of FIG. 57, the medical image display apparatus 100 may display the UI 5711 having a size corresponding to the user 5-1. As shown in a portion 5720, when the user holding the medical image display apparatus 100 changes from the user 5-1 to the user 5-2, the medical image display apparatus 100 may display the UI 5721 having a size corresponding to a touch range of a finger of the user 5-2.

As a user holding the medical image display apparatus 100, a strength of a finger touching the touch screen 110, or a posture of a finger touching the touch screen 110 changes, a contact area of a finger with the touch screen 110 when the finger touches the touch screen 110 may vary accordingly.

Thus, the medical image display apparatus 100 may display a UI based on a contact area of a user's finger.

FIG. 58 is a flowchart of a method of providing a UI including an icon having a size corresponding to a contact area of a user's finger, according to an exemplary embodiment.

Referring to FIG. 58, the medical image display apparatus 100 may acquire information about a contact area of a user's finger (S5810).

The information about the contact area of user's finger may include information about a minimum area of user's finger with the touch screen 110 when the user's finger touches the touch screen 110. In some exemplary embodiments, the information about the contact area of user's finger may include information about an average contact area of user's finger with the touch screen 110 when the user's finger touches the touch screen 110.

Furthermore, as a thickness of a finger increases, a contact area of the finger with the touch screen 110 may increase. Furthermore, as a strength of a finger touching the touch screen 110 increases, a contact area of finger with the touch screen 110 may increase. As a finger touching the touch screen 110 becomes more perpendicular to the touch screen 110, a contact area of a finger with the touch screen 110 may decrease.

Thus, the medical image display apparatus 100 may acquire information about at least one of a thickness of a finger, a strength of a finger touching the touch screen 110, and a posture of a finger touching the touch screen 110 as information about a contact area of a user's finger.

The medical image display apparatus 110 may acquire the information about a contact area of a finger from a memory included therein, a memory of an external device, or an external server. In some exemplary embodiments, the medical image display apparatus 100 may acquire the information about the contact area of the finger by analyzing a touch gesture received from the user in response to a guide image. For example, the medical image display apparatus 100 may acquire information about the contact area of the finger by analyzing a tap touch received from the user. In addition, the medical image display apparatus 100 may receive the information about the contact area of the finger directly from the user.

When a user holding the medical image display apparatus 100 changes to a new user, the medical image display apparatus 100 may acquire information about a contact area of a user's finger again and provide a UI suitable for the new user. In some exemplary embodiments, when a position of a user's hand used to grip the medical image display apparatus 100 is changed, the medical image display apparatus 100 may acquire information about a contact area of a user's finger again and provide a UI suitable for the changed position of the user's hand.

The medical image display apparatus 100 may determine a UI including at least one icon having a size corresponding to the contact area of the user's finger (S5820).

For example, the medical image display apparatus 100 may determine a size of an icon corresponding to the contact area of the user's finger. The medical image display apparatus 100 may determine the number of icons to be included a UI based on the contact area of the user's finger. The medical image display apparatus 100 may determine a UI including a number of icons corresponding to the contact area of the user's finger.

For example, as illustrated in FIG. 5, the medical image display apparatus 100 may select a UI having a size corresponding to a finger-touchable range from among a plurality of UIs related to a medical image. The medical image display apparatus 100 may determine the number of icons to be included in the selected UI, based on a contact area of a user's finger.

If more icons are included in the UI according to the contact area of the user's finger the UI may provide a larger number of functions. As the contact area of the user's finger decreases, the medical image display apparatus may determine a UI that provides a larger number of functions.

As another example, the medical image display apparatus 100 may select from among a plurality of UIs related to a medical image a UI including at least one icon having a size corresponding to a contact area of a user's finger.

The plurality of UIs related to a medical image includes at least one of a GUI for setting parameters related to the medical image, a GUI for controlling an external device or server connected to the medical image display apparatus 100, and a UI for displaying information about the medical image.

The medical image display apparatus 100 may select a UI including an icon having a size corresponding to a contact area of a user's finger based on a result of comparing the contact area of the user's finger to a threshold value. The threshold value may be predetermined as a default value or may be set by the user. For example, if the contact area of the user's finger is greater than the threshold value, the medical image display apparatus 100 may select a UI including an icon having a first size that is greater than the threshold value. In some exemplary embodiments, if the contact area of the user's finger is less than or equal to the threshold value, the medical image display apparatus 100 may select a UI including an icon having a second size corresponding to the threshold value.

In some exemplary embodiments, the medical image display apparatus 100 may determine a UI including at least one icon having a size corresponding to the contact area of the user's finger, so that a difference between the contact area of the user's finger and a size of the icon falls within a certain range.

For example, as the contact area of the user's finger increases, the medical image display apparatus 100 may select a UI including an icon having a larger size. As the contact area of the user's finger decreases, the medical image display apparatus 100 may select a UI including an icon having a smaller size.

The medical image display apparatus 100 may display the determined UI determined in operation S5820 previously (S5830). The medical image display apparatus 100 may display the determined UI at a position determined based on a position of a user's hand or finger.

To allow a medical image provided via the medical image display apparatus 100 to be used for diagnosis or treatment of a disease, the medical image has to be provided to the user without being distorted. For example, if a UI is displayed to overlap a medical image, accuracy of diagnosis and treatment of a disease may be degraded. Thus, the medical image display apparatus 100 may change a position where the medical image is to be displayed so that a selected UI and the medical image does not overlap each other, based on a position where the selected UI is displayed.

FIG. 59 illustrates examples of UIs 5911 and 5921, each including an icon having a size corresponding to a contact area of a user's finger, according to an exemplary embodiment.

Referring to FIG. 59, the medical image display apparatus 100 may select the UIs 5911 and 5921 from among a plurality of UIs based on a size of a first region corresponding to a finger-touchable range and display the selected UIs 5911 and 5921.

As shown in a portion 5910, when a contact area of a user's finger corresponds to a circle having a diameter of 1 cm, the medical image display apparatus 100 may determine two icons 5901 each having the same or similar size as the contact area of the user's finger. The medical image display apparatus 100 may also determine the UI 5911 configured to include the two icons 5901 based on the size of the first region and the size of the icons 5901. As shown in the portion 5910, the medical image display apparatus 100 may display on the touch screen 110 the UI 5911 including the two icons 5901, each having a size corresponding to the contact area of the user's finger. The UI 5911 may provide a function of setting an operating mode to a live mode or a freeze mode.

As shown in a portion 5920, when a contact area of a user's finger corresponds to a circle having a diameter of 0.5 cm, the medical image display apparatus 100 may determine four icons 5902 each having the same size as the contact area of the user's finger. The medical image display apparatus 100 may also determine the UI 5921 configured to include the four icons 5902 based on the sizes of the first region and the icons 5902. As shown in the portion 5920, the medical image display apparatus 100 may display on the touch screen 110 the UI 5921 including the four icons 5902, each having a size corresponding to the contact area of the user's finger.

The UI 5921 may provide a function of setting an operating mode to a live mode or a freeze mode and a function of adjusting intensity of an ultrasound signal.

As seen in the portions 5910 and 5920, as the contact area of the user's finger decreases, the medical image display apparatus 100 may display a UI configured to provide more functions.

It has been described above that the medical image display apparatus 100 is connected to the ultrasound diagnosis device 11 or the ultrasound probe 12 and provides a UI related to an ultrasound image.
